Case Study 1
1.Briefly describe the three major layers of skin that make up healthy skin The three layers that make up healthy skin: Epidermis, Dermis and Hypodermis. Epidermis is composed of keratinized, stratified squamous epithelium. This layer provides a thick, water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense, irregular, fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels, nerve ending, and epidermally derived cutaneous oranges such as sweat glands, sebaceous glands and hair follicles. The last layer is Hypodermis this layer is composed primarily of loose dead skin. The fat layer provides cushioning and insulation for underlying organs.

2.Briefly describes the extent of damage seen in first-degree burns, second-degree burns, and third degree burns. First degree burns only epidermis is damaged and skin is red and swollen. Second-degree burns epidermis and upper dermis are damaged. Third-degree burns destroys entire skin layer; burned area is painless and the burn is gray-white or black.

3.Why was the girl relatively pain-free when she woke up?
Due to having third-degree burns on 15% off her body and since third degree burns are painless her body was probably numb and in shock as well. Since the second degree burns aren’t as deep she may feel pain in these areas because the nerves are still intact.

4.Explain why this patient’s blood pressure was so low and her heart rate was so high upon arrival at the emergency room. Due to the burns she lost her water tight protective covering and significant shift of water from her blood stream due to having low blood volume her heart has to work harder (high heart rate) to try and pump more blood.

5.Why was it important to immediately administer intravenous fluids to this girl? She will need IV fluids to replace the fluid she lost due to the burns covering her body. She could go into shock without...
